Managers Jennifer and Brendan Pelto later confirmed that the theater, 1937 Lakeshore, had its last two showings Sunday night.

After nearly five years in operation, the theater closed on showings of 'My Week With Marilyn' and 'Like Crazy'.

"It's bittersweet to end on such great films," said Brendan Pelto.

Shortly after the announcement was made on the social media website, the theater's Facebook page lit up with comments. More than 100 users expressed sadness at the closure.

The theater was unable to stay open despite upgrades made in the past several months. In June, owners added 3D compatibilities to the screens and in October began showing first-run films to play head-to-head with Norton Shores' Cinema Carousel.

In Feb. 2010, the struggling venue raised more than $6,000 through a fundraiser that featured an appearance by filmmaker Michael Moore.

"It goes to show that if you want to have locally-owned business in your community, you have to support them," Jennifer Pelto said.

The Facebook post stated, "Thank you for your understanding -- this was not an easy decision for those involved with the Harbor Theater."

It also expressed gratitude to "our wonderful patrons."

The couple said more information about the closure will be released in the coming days.
